Product details
Overview
MLX90422GVS-ADD-038-RE from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary position sensing. It integrates Triaxis® Hall front end, DSP-based signal conditioning, and SENT (SAE J2716 APR2016) output. Key confirmed parameters: operating temperature −40°C to +160°C, supply voltage 4.5–5.5 V, SENT tick time fixed at 3 μs, angular accuracy ≤ ±0.5° over full range, and DMP-4 package with 4-pin PCB-less construction.
For engineers reviewing the MLX90422GVS-ADD-038-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, pin-level design meaning, automotive-grade functional safety (ASIL B), SENT protocol timing, and real-world use cases in throttle, pedal, and steering position sensing.
Technical Context
The MLX90422GVS-ADD-038-RE uses Triaxis® Hall technology to measure all three magnetic field components (Bx, By, Bz) and computes absolute angular position via on-chip DSP. Its programmable linear transfer characteristic supports up to 17-point calibration, enabling precise mapping of magnet motion to output angle.
It operates in SENT mode with fixed 3 μs tick time and default A.3 (H.4) format, delivering synchronized acquisition with 2 angle measurements per frame. The DMP-4 package variant features dual-mold construction, built-in decoupling, and pin-to-pin compatibility with prior Triaxis® generations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90421GVS-ADD-038-RE | Single-die version with identical DMP-4 package, SENT A.3 output, and same 17-point linearization but no dual-die redundancy | Lacks ASIL B certification and failsafe diagnostics; not approved for ASIL-B systems | Select when cost sensitivity outweighs functional safety requirements and redundancy is not mandated |
| AMS AS5600-WSCT | I²C output only, no SENT; 12-bit resolution but no on-chip linearization or ASIL qualification; max operating temp +85°C | Restricted to cabin or low-temp industrial use; requires host MCU for calibration and diagnostics | Choose only for non-automotive, non-safety-critical rotary encoders where I²C interface suffices |
Compared with MLX90422GVS-ADD-038-RE, the MLX90421GVS-ADD-038-RE omits dual-die safety mechanisms and ASIL B certification, while the AMS AS5600-WSCT lacks SENT output, automotive temperature rating, and embedded signal processing - making MLX90422GVS-ADD-038-RE uniquely suited for safety-critical, high-temp, production automotive position sensing.

Does the MLX90422GVS-ADD-038-RE support SENT protocol configuration?
Yes, the MLX90422GVS-ADD-038-RE implements SENT per SAE J2716 APR2016 with fixed 3 μs tick time and default A.3 (H.4) format. It supports both SENT with pause (synchronous acquisition) and SENT without pause (asynchronous acquisition), programmable via NVRAM. Frame content, CRC, and diagnostic fields are fully configurable.
What package type does MLX90422GVS-ADD-038-RE use and what are its key advantages?
The MLX90422GVS-ADD-038-RE uses the DMP-4 (Dual Mold Package) - a 4-pin, PCB-less dual-mold construction with integrated decoupling capacitance. Its advantages include reduced board space, elimination of external capacitors, improved vibration resistance, and pin-to-pin compatibility with legacy Triaxis® sensors, simplifying migration.
Is the MLX90422GVS-ADD-038-RE certified for functional safety applications?
Yes, the MLX90422GVS-ADD-038-RE is certified as ISO 26262 ASIL B Safety Element out of Context (SEooC).
